sporinite

Main macerals of hydrocarbon generation are sporinite, cutinite, alginite, bituminite, liptodetrinite and desmocollnite in source rocks from Jurassic coal measure in Northwest China.

西侏罗纪煤系层中主要的生组分是孢子体、角质体、藻类体、沥青质体、碎屑类体、基质镜质体等，而树体、木栓质体等早期低熟生油组分含量很低。

A small quantity of sporinite and cutinite were identified in addition to the majority of the hydrocarbon-forming micro-components that mainly occurred as matrix vitrinites.

源岩主要生组分为基质镜质体，少量孢子体、角质体和碎屑壳质体。
